长安cs35暖风不热和防冻液有关系吗
推荐回答（4个）
有关系。
冷却液俗称防冻液，汽车空调暖风就来自于此，原理和家用空调制热不一样。汽车暖风循环是在发动机冷却液小循环管路中并联一条管路，管路中连接暖风水箱，鼓风机吹暖风水箱后产生暖风，空调暖风就是如此而来。冷却系统缺冷却液是导致暖风不热最常见也是最容易解决的故障现象。
在设计发动力冷却系统时，工程师会优先考虑发动机散热，然后是暖风正常工作。在冷却液不足时，会优先让冷却液在发动机中循环，此时暖风循环管路中就没“水”了，暖风水箱中大部分是气，此时空调暖风自然不热。
从发动机仓内部就能看到暖风水箱的位置，有些车型暖风水箱位置会高于缸体，和缸盖持平或高于缸盖，这样就保证在冷却液不足的情况下优先使冷却液在缸体、缸盖中循环，补足冷却液后，暖风水箱中充满滚烫的冷却液，暖风自然会热起来。
扩展资料：
暖风跟冷风的工作原理不同。冷风是通过压缩机增压使制冷剂液化后汽化，并吸收空气中大量的热量而形成的；冷风打开时，压缩机带轮带动压缩机工作，增加发动机负荷，要耗费一定量的燃油。
而暖风则是来自于发动机工作时产生的热量：当发动机的冷却系统给发动机散热后，通过风扇将散出的热量送入车内，形成暖风；在不使用暖风时，风扇停转，热风口关闭，散出的热量就会完全散入大气中。所以，汽车暖风属于废物再利用，不会耗费油量。

很高兴为你解答，你先暂时不要考虑暖风不热和防冻液有没有关系，我给你分析几点第一，发动机水温正常的情况下你可以打开前面引擎盖用手摸摸通往暖风水箱的两个水管是不是烫手如果这两个水管有温差那就是暖风水箱有堵塞只能换风机里面的小水箱，第二你要检查你的暖风箱是否在正常工作出不出风，第三如果你换防冻液来，要检查一下是不是排气没排完呢，还有节温器打开了吗现在回答你提问的问题，暖风不热是和防冻液有关系的，防冻液脏时间长了会堵水箱劣质的防冻液也不要用时间长了会有水垢主要是沸点达不到会开锅的建议你用好点的防冻液，最好是到修理厂检查一下如果小水箱堵了你自己是弄不来的谢谢【汽车有问题，问汽车大师。4S店专业技师，10分钟解决。】
你好，有一定关系，建议检查节温器和暖风水箱，防冻液2年4万公里需要更换，希望能帮到你，感谢你对汽车大师的支持，祝你生活愉快【汽车有问题，问汽车大师。4S店专业技师，10分钟解决。】
这个没有关系的，主要看水箱是否堵塞，第二看转换冷暖风的翻版是否打到热的上面。【汽车有问题，问汽车大师。4S店专业技师，10分钟解决。】
